When an electric heater isemployed, the lead in and lead out wires may conveniently extend throughthis opening 12, instead of the gas pipe connection 16. f.

17 indicates the dry closet container proper, having a suitable bail orhandle 18, with the usual removable apertured seat 19, and hinged cover20 therefor.

Theupper rear peripheral wall of this container' is provided with a foulair outlet 21, terminating in a projecting tubular extension or uppercoupling pipe member 22, which is so spaced vertically, relatively tothe lower conduit pipe connection 13, that these upper and lower pipesaline in axial registration, respectively, with the coupling member 5and aperture 4 of the base standard, when the parts are assembled.

vrlhe foul air outlet 21 ispreferably encompassed by a shield element23, which is in the nature of a curved platespaced interiorly of therear peripheral wall of the container, and forming a pocket terminatingsubstantially above the foul air outlet,

with an penlng 24: intermediate of thel outlet proper and the extremeupper portion of the container. This shield not only increases theworking capacity of the container, which may now be filled above theposition of the foul air outlet, but also the arrangement is such that asuctional down draft is provided for, as ,will later appear, functioningto draw d own and out, more effectively, any foul air or. gases arisingand accumulating above the outlet opening,

and finally escaping around the seat closure.

to the interior of the room, which would be manifestly objectionable.

vThe bottom of the container 17 rests above and closes the open top ofthe pan 10, being guided, centered, and supported in place by means ofthe offset detachably attaching projections 25, as clearly shown.

The projecting end of the base standard coupling pipe member 5 isoutwardly flanged, as at 26, and is engaged by the inturned flange 27 ofan enlarged coupling union 28 rotatably mounted on the pipe 5, andadapted to receive the projecting end of the container coupling pipemember 22.

The latter pipe member 22 is provided, on each side thereof, with anoutwardly depressed lug 29, being of lengths approximately aboutone-fourth of its circumference, and these lugs 29 are disposedin thepath of a spiral, functioning with a screwthreaded or wedging action inassociation with complementary internally projecting pins or lugs 30-31carried by the inner wall face of the coupling member or union 28, aswill be clearly understood from the drawings.

' In assembling or installing the closet, the pan 10 is properlypositioned, with 'the projecting end of the conduit pipe fitted in or inline with the lower opening 4L of the base standard pipe 1. Thecontainer 17 is then simply seated thereo-ver, with the upper pipecoupling members 5 and 22 registering in axial alinement but with theiradjacent ends slightly spaced apart, as seen in Fig. 5. Upon therotation of the union 28 to the left, .in Fig. 5, it will be observedthat the engaging .pin 30 thereof will ride up the incline of itsspirally associated lug 29, while the opposite pin 31 V'will reverselyride down its complementarylug 29, causing the ends of the couplingmembers 5 and 22'to be'tightly drawn together, and the whole xture heldsecurely in that position, as seen in Figs. 1,6 and 8. Thus it Vwill beapparentthat an effective coupling' may be speedily made with little orno trouble or effort, while detachment of the container, for emptyingand cleaning, may also be facilely accomplished. i

When so set up,.a suitable liquid deodorizer and germicide may beintroduced into the container as usual, if desired, and this regardlessof whether or not lthe heating feature is utilized at all times, for theimproved type of exceedingly effective joinder betweenv the containerand the base standard, so that this improved arrangement alone wouldprovide for conveying olf the foul odors by way of the vent pipe.

j When the heater feature is placed in operation, however, it will notonly tend to evaporate and reduce the contents of the container, whiledriving out therefrom foul odors and destroying' the germ life thereof,but also a more intense draft will be created through the vent pipe, byway of the upper coupling makes au roo lower conduit pipe 13conununicating with the hollow base standard, providing a positivesuctional force through the upper coupling 5-22, and hence a down draftover the-shield 23, thus sucking out all foul odors and gases from theinterior of the container. Obviously the lower damper 6 will control thedegree of this draft, while the upper damper 7 will likewise control thesuctional force through the upper coupling, when the dampers areproperly adjusted.

With the foregoing complete disclosure, it is believed that any furtherdescription would only .be superfluous and prolix, and while it will beunderstood that I do not make any broad claims to the detachablecoupling up of a dry closet container with a vent pipe generally, at thesame time, I do not limit myself to the exact details as set forth,excepting as come within the purview of the ensuing claims, when viewedin the light of the specification and contemplating a fair range ofequivalents. y

What I do claim, as new and practicable, is

1. In dry closet fixtures, the combination with a hollow base standardforming the bottom section of a vent conduit; of a container andsuitable apertured seat therefor, said container having a foul airoutlet through its upper peripheral wall; tubular coupling meansextending from said foul air outlet to the upper portion of said basestandard, providing a vent passage therebetween; and heating means forsaid container, functioning to evaporate the contents thereof,substantially as described.`

2. In dry closet fixtures, the combination with a hollow base standardforming the bottom section of a vent conduit; of a container andsuitable apertured seat therefor, said container having a foul airoutlet through its upper peripheral wall; tubular coupling meansextending from said foul air outlet to the upper portion of said basestandard, providing a vent passage therebetween; heating means for saidcontainer functioning to evaporate the contents thereof; and a draftpipe connection leading from said heating means to said hollow basestandard for supplyin hot air to the latter, substantially as descri ed.
